TIA Claudio Rachiele IW0DZG (Embedded image moved to Thomas Brandon file: 08/04/99 02:22 AM pic09036.pcx) Please respond to pic microcontroller discussion list To: PICLIST@MITVMA.MIT.EDU cc: (bcc: Claudio Rachiele IW0DZG/Italy/IBM) Subject: Re: PIC's and CDROM's Try the following: The MPX (http://www.angelfire.com/pa2/mpx/) -"The MPX player is a stand alone MPEG audio player. the unit will be capable of playing CDR's that will be burned with .mp3 and .mp2 files burned on to them." With technical links. It is actually based on a "Hitachi H8/300 8-bit MPU running at 16mhz" but the technical details should be useful. MP3Tech (http://www.spectsoft.com/mp3tech/) has some embedded MP3 related links. ftp://fission.dt.wdc.com/pub/standards/x3t13/project/ -Technical documents on ATA/ATAPI and other syandards. Not sure what all the files are but I know the following d1321r1a = AT Attachment with Packet Interface - 5 (ATA/ATAPI-5) Standards - There are also documents on ATAPI over IEEE 1394 (=Firewire = very fast (500Mb/s from bad memory) USB) but I don't know which one. http://www.nomad.ee/micros/ - Info on an 8052 IDE interface. Started off using a PIC but changed due to PIC limitations. Hardware interface fully implemented, software interface partially interfaced. Also, some info was sent round offlist on "How to connect an IDE disk to a microcontroller using an 8255". If you did not recieve it email me off list and I will send you (or anyone else interested) a copy (it's 111Kb so I won't send it to the list). I recieved this info from Omar Martinez (hope I'm giving credit to the right person. Apologies if not). This is on my list of things to do so I would be interested to know how you go.
